What the vulnerability does
The Comment Genius plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the `$_SERVER['PHP_SELF']` parameter in all versions up to, and including, 1.2.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Comment Genius versions 1.2.5 and earlier contain a cross-site scripting (XSS) vulnerability in how it handles user input. An attacker can inject malicious scripts that execute in other users' browsers when they view affected pages. The vulnerability requires user interaction—victims must visit a crafted link or page. The impact is limited to session hijacking or credential theft from affected users.
What an attacker can do
Inject malicious scripts that run in other users' browsers to steal session tokens or credentials.
Potential impact on your site
